Description

Technical Field

[0001] This utility model belongs to the field of baby product technology, specifically referring to a folding baby walker. Background Technology

[0002] Baby walkers are an important means of transportation for babies before they learn to walk. They can help babies practice walking, bring them fun, and assist parents in caring for their children. They are an essential baby product for parents in raising their children.

[0003] Existing baby walkers are bulky and inconvenient to carry. Even though there are baby walkers on the market that can be folded up to reduce their overall size, the folding structure is prone to damage and instability after prolonged use. In addition, the folding method is relatively simple and still takes up a lot of space. Summary of the Invention

[0004] The purpose of this invention is to solve the problems existing in the prior art and to provide a foldable walker that occupies little space when folded.

[0005] The purpose of this utility model is achieved as follows:

[0006] A folding baby walker includes an annular upper support and a lower support. Both sides of the bottom of the upper support are hinged with inwardly bent upper side frames. Both sides of the upper end of the lower support are hinged with inwardly bent lower side frames. A hinge post is fixed to the bottom of the upper side frame. The inner wall of the lower side frame has hinge holes adapted to the hinge posts. A slider is formed on the outer wall of the upper side frame above the hinge posts. The inner wall of the lower side frame has a semi-circular limiting groove for sliding the slider, with the opening direction of the limiting groove being either directly forward or directly backward.

[0007] The present invention is further configured such that the upper frame includes an upper frame box and an upper cover covering the rear of the upper frame box. A zipper bracket is provided inside the upper frame box. The zipper bracket includes a handle extending from the top of the upper frame box and a locking torsion bracket abutting its rear bottom. Limiting blocks extending from the front side wall of the upper frame box are provided at both ends of the locking torsion bracket. A compression spring is provided between the locking torsion bracket and the upper cover. An inclined block is formed at the bottom of the zipper bracket. The inclined surface of the inclined block abuts against the bottom of the locking torsion bracket. When the handle pulls the zipper bracket upward, the inclined surface of the inclined block drives the locking torsion bracket to overcome the spring force of the compression spring and move the locking torsion bracket to the rear. The limiting block no longer extends from the front side wall of the upper frame box. The lower frame includes a lower frame box and a lower cover covering the rear of the lower frame box. A limiting hole corresponding to the limiting block is provided on the lower cover.

[0008] The present invention is further configured such that there are two compression springs, one end of which abuts against the rear side of the limiting block, and the other side abuts against the front side wall of the upper cover.

[0009] The present invention is further configured such that a fixing ring is formed in the middle of the locking frame and sleeved on the rear side of the hinge hole, and the limiting blocks are formed at both ends of the fixing ring.

[0010] The present invention is further configured such that the hinge hole includes an adjusting elongated hole provided on the lower side cover for the hinge post to slide up and down, and the number of limiting holes is three sets, with each set of limiting holes being provided on both sides of the adjusting elongated hole.

[0011] The present invention is further configured such that the hinge post is a cylinder, and the side wall of the hinge post is formed with parallel end faces; the top of the adjusting elongated hole is a circular hole, and the lower end of the circular hole extends downward to form a strip-shaped hole; the diameter of the circular hole is the same as the diameter of the hinge post; and the distance between the two end faces of the hinge post is the same as the lateral width of the strip-shaped hole.

[0012] The present invention is further configured such that hinged baffles are formed at both ends of the lower end of the upper bracket and both ends of the upper end of the lower bracket.

[0013] The present invention is further configured such that the planar area of ​​the upper bracket is smaller than that of the lower bracket, and when the upper bracket is rotated 180°, the upper bracket is embedded in the lower bracket.

[0014] The present invention is further configured such that a toy platform is detachably connected to the upper bracket, and a number of toys are arranged on the toy platform; and a number of casters are fixed to the lower end of the lower bracket.

[0015] The outstanding and beneficial technical effects of this utility model compared to the prior art are:

[0016] 1. The folding walker provided by this utility model utilizes the upper side frame to rotate on the top of the lower side frame via a hinged column, which can flip the upper support frame to one side of the lower support frame, thereby reducing the height and making it easier to store. At the same time, the upper and lower side frames are connected to the two ends of the upper and lower support frames by hinges. After flipping the upper support frame, the upper and lower side frames can be bent inward for further folding and storage, taking up less space.

[0017] 2. The present invention further provides a matching limiting block and limiting hole between the upper side frame and the lower side frame to lock the upper and lower side frames, while the zipper bracket in the upper side frame can lock and open the limiting block.

[0018] 3. This utility model further incorporates a locking torsion frame fitted onto a fixing ring behind the hinge hole, ensuring that the locking torsion frame does not deviate in its direction of movement during movement; and provides compression springs at both ends to make the movement of the drive limit block more stable, and to ensure that both limit blocks can simultaneously bear force on the rear side; and employs multiple sets of limit holes to enable the upper frame to move up and down on the lower frame, with easy adjustment, suitable for infants and children of different ages.

[0019] 4. The hinged baffle provided in this utility model can restrict the upper and lower side frames from folding outward, achieving the requirement of folding only 90°. Attached Figure Description

[0032] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. See also: Figure 1 — Figure 5 :

[0033] A folding baby walker includes an annular upper support frame 1 and a lower support frame 2. The upper support frame 1 has inwardly bent upper side frames 3 hinged to both sides of its bottom. The lower support frame 2 has inwardly bent lower side frames 4 hinged to both sides of its upper end. A hinge post 5 is fixed to the bottom of the upper side frame 3. The inner wall of the lower side frame 4 has a hinge hole 6 that matches the hinge post 5. A slider 30 is formed on the outer wall of the upper side frame 3, located above the hinge post 5. The inner wall of the lower side frame 4 has a semi-circular arc-shaped limiting groove 40 for sliding the slider 30. The opening direction of the limiting groove 40 is either directly in front or directly behind.

[0034] When storing the vehicle after use, rotate the upper bracket forward or backward by 90 degrees, following the opening direction of the limiting slide 40. After rotation, fold the upper and lower side frames inward to further reduce the height of the folding snow walker.

[0035] Preferably, the upper frame 3 includes an upper frame box 31 and an upper cover 32 covering the rear side of the upper frame box 31. A zipper bracket 33 is provided inside the upper frame box 31. The zipper bracket 33 includes a handle portion 330 extending from the top of the upper frame box 31, and a locking torsion bracket 34 abutting its rear bottom. Limiting blocks 340 extending from the front sidewall of the upper frame box 31 are provided at both ends of the locking torsion bracket 34. A compression spring 35 is provided between the locking torsion bracket 34 and the upper cover 32. An inclined block 3 is formed at the bottom of the zipper bracket 33. 31. The inclined surface of the inclined block 331 abuts against the bottom of the locking frame 34. When the handle 330 pulls the zipper bracket 33 upward, the inclined surface of the inclined block 331 drives the locking frame 34 to overcome the elastic force of the compression spring 35 and move the locking frame 34 to the rear. The limiting block 340 no longer extends out of the front side wall of the upper frame box 31. The lower frame 4 includes a lower frame box 41 and a lower cover 42 covering the rear side of the lower frame box 41. The lower cover 42 has a limiting hole 420 corresponding to the limiting block 340.

[0036] Between the upper and lower side frames, by pulling the handle 330 on the pull lock bracket, the inclined block 331 is driven to move upward. The locking torsion bracket 34, which abuts against the inclined surface of the inclined block 331, moves towards the upper side cover. The moving locking torsion bracket drives the movement of the limiting block 340. The limiting block 340 is no longer embedded in the limiting hole 420, thus no longer locking the rotation of the upper and lower side frames. In addition, the compression spring 35 plays a reset role, requiring the user to maintain the upward pulling action during the pull-up process.

[0037] Preferably, there are two compression springs 35, one end of which abuts against the rear side of the limiting block 340, and the other side abuts against the front side wall of the upper cover 32.

[0038] The locking effect of a single limit block 340 or the stress borne by the limit block is relatively large, so two limit blocks are set to alleviate the stability of the upper and lower side frames during the support process.

[0039] Preferably, a fixing ring 341 is formed in the middle of the locking torsion frame 34 and sleeved on the rear side of the hinge hole, and the limiting blocks 340 are formed at both ends of the fixing ring 341. The fixing ring 341 is used to prevent the locking torsion frame 34 from moving up and down, and to fix it in place so that the locking torsion frame can only move back and forth.

[0040] Preferably, the hinge hole 6 includes an adjusting elongated hole 60 provided on the lower cover 42 for the hinge post 5 to slide up and down, and the number of limiting holes 420 is three sets, with each set of limiting holes 420 being provided on both sides of the adjusting elongated hole 60.

[0041] During implementation, the three sets of limiting holes 420 are used to adjust the height to accommodate infants and children of different heights.

[0042] Preferably, the hinge post 5 is a cylinder, and the side wall of the hinge post 5 is formed with parallel end faces 50. The top of the adjusting elongated hole 60 is a circular hole, and the lower end of the circular hole extends downward to form a strip-shaped hole. The diameter of the circular hole is the same as the diameter of the cross-section of the hinge post 5, and the distance between the two end faces of the hinge post 5 is the same as the lateral width of the strip-shaped hole.

[0043] Since the hinge pin needs to be moved up and down when adjusting the height, the adjustment hole includes two shapes: the strip hole is to facilitate the up and down movement of the hinge pin, and the round hole is to facilitate the rotation of the hinge pin.

[0044] Preferably, both ends of the lower end of the upper bracket 1 and both ends of the upper end of the lower bracket 2 are formed with hinge baffles 10. The purpose of the hinge baffles is to limit the rotation range of the upper and lower brackets to only 0° to 90° during the folding process.

[0045] Preferably, the planar area of ​​the upper bracket 1 is smaller than that of the lower bracket 2, and when the upper bracket 1 rotates 180°, the upper bracket 1 is embedded in the lower bracket 2. This achieves a smaller footprint.

[0046] Preferably, a toy platform is detachably connected to the upper bracket 1, and several toys are arranged on the toy platform; several casters are fixed to the lower end of the lower bracket 2.

[0047] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection of the present utility model.
